NHED STATES WILLIAM TWIGG, OF FOREST, INDIANA.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 668,272, dated February 19, 1901.

Application filed August 28, 1899. Serial No. 728,158. (No model.)

To a whom it may concern:

Be it known that I, WILLIAM TWIGG, a citizen of the United States, and a resident of Forest, in the county of Clinton and State of Indiana, have invented certain new and useful Improvements in Wrenches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a perspective view of the invention as applied. Fig. 2 is a central vertical longitudinal section of the same upon an enlarged scale. Fig. 3 is a detail view of the wrench-socket m.

This invention has relation to wrenches for removing taps from wheel-tires; and it consists in the novel construction and combination of parts, as hereinafter set forth.

In the annexed drawings, illustrating this invention, the letter A designates a post or standard which supports the body B of the wrench and to which said body B is secured at its upper portion. The lower portion of this standard may be adjustable in order that its length may be varied.

The body B of the Wrench consists of a U- shaped bracket 0, having upper and lower extensions D, which are secured to the standard by means of suitable bolts e, or the standard and base may be both made of iron and in one piece.

F indicates a shaft having a vertical gearwheel G, said shaft being extended through and having bearings in the outer wall of the bracket 0 and having on its free end a vertically-operating crank-handle I-L whereby it may be turned.

K indicates a second vertical shaft at right angles to the shaft F and also extended through and having bearings in the bracket 0. This shaft carries a horizontal gear-wheel J, which is at right angles to the wheel G and engages the latter. That portion of the shaft K which extends beyond the iron body B at its upper part is provided with or forms the wrench-socket m, which is adapted to engage a tap of the wheel-tire from the inside of the felly.

To lugs of the upper extension D of the bracket, or above the latter, is pivoted the end of a pressure-lever L, extending outwardly upon the same side of the post as the operating-crank, said lever having a pressure boss or projection 19, which is, when said lever is brought down to its work, at an even distance from the standard with the wrench-socket m and opposite thereto. The handle portion of this lever is bent upwardly at substantially right angles thereto.

The pressure-lever L works in a vertical plane at right angles to the plane of movement of the operating-crank H.

In operating the device the standard is placed on the inside of the wheel andin such position and so adjusted that the wrenchsocket will readily engage the tap on the inside of the felly at the upper portion of the wheel. The lever L being brought down upon the head of the bolt from the outside of the wheel, the engagement of the wrench is rendered firm and is so held by the operator with one hand upon said lever while he turns with his other hand the crank-handle, which causes rotation of the wrench-socket, whereby the engaged tap is removed.

It will be noted that by extending the pres sure-lever outwardly upon the same side of the supporting-post as the operating-crank the operator is not obliged to straddle the post and the Wheel being operated upon in using the wrench. The pressure-lever has its handle portion bent upwardly therefrom in order to prevent interference between the operating-crank and the pressure-lever.

Owing to the fact that the crank I-I operates vertically upon the same side of the supportingpost as the wheel being operated upon the operator can maintain his position closer to the wheel and with no interference handle portion of the pressure-lever L facilitates the maintenance of this position by the operator.

It will be noted that my pressure-lever consists of a main portion extended outwardly from the supporting'post, in register when in action with the path of movement of the operating-crank, of a length less than the distance from post to crank and having the clutch projection, and of a handle portion extended upwardly at substantially right angles to said main portion. These features in connection with features heretofore mentioned enable the wheel to be vertically disposed,

avoid the necessity for the operator to stradbring his weight to bear in pressing such lever downwardly with great effect and ease to himself.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s

A wrench for the purpose described, con sisting in the combination with the support ing-post, having a bracket, of a vertical gearwheel journaled upon said bracket, a crank operating in a vertical plane upon the shaft of said wheel, a horizontal gear-Wheel meshing with said first-named wheel, and having "jection, and of a handle portion extended upwardly at substantially right angles to said main portion thereof, whereby the wheel to be operated upon may be vertically disposed, the operator is not required to straddle the post or the wheel with his arms, any interference of the crank in its movement with the person or arm of the operator is avoided, and the pressure-lever may be operated with a straight arm upwardly extended, to bring the weight of the operator to bear with great eifect and ease, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM TWIGG.
